I just bought and took delivery of a new bx23s last week. As of this morning it had 4 hours on it. I was moving some dirt when I noticed the tach would bounce and then all of a sudden the tach doesnt move no matter what speed the tractor is in. The hour meter displays but did not add any time to the original 4 hours. Im not sure if the fuel gauge is working and the temp stayed in the middle where it normally runs. Any ideas before I call the dealer in the morning?
